1.1 This specification covers uncoated, deformed, stress-relieved, and stress-relieved low-relaxation wire for use as prestressed tendons in concrete railroad ties.

1.2 The values stated in either-inch-pound units or SI units are to be regarded separately as standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values for the two systems may result in non-conformance with the specification.


This specification covers uncoated, deformed, stress-relieved, and low-relaxation wire for use as prestressed tendons in concrete railroad ties. Deformed wires with nominal diameters shall be supplied in coils and shall conform to specified values of breaking strength requirements. The relaxation losses of normal stress-relieved and low-relaxation stress-relieved wires should not exceed the specified limits. The two acceptable types of deformed wire shall have specific dimensions of deformations, where the depth of indent shall be the average depth of six or more random indents measured at maximum depth. The material shall be tested on and shall conform to specified values of the following mechanical properties: breaking strength, load at 1% extension, elongation, bending, and relaxation.
